      platform: numeric_state
      entity_id: sensor.kitchen_circuit_power
      above: 3000
    action:
      service: notify.mobile_app
      data:
        message: "Kitchen circuit drawing excessive power: {{ states('sensor.kitchen_circuit_power') }}W"

Daily Energy Report

Summarize daily energy consumption across TONGOU circuits:

automation:
  - alias: "Daily Energy Report"
    trigger:
      platform: time
      at: "22:00:00"
    action:
      service: notify.mobile_app
      data:
        message: "Today's consumption - Kitchen: {{ states('sensor.kitchen_circuit_energy') }}kWh"

Smart Circuit Control Based on Time

Automatically manage circuits based on schedules:

automation:
  - alias: "Evening Lighting Schedule"
    trigger:
      platform: time
      at: "18:00:00"
    action:
      service: switch.turn_on
      target:
        entity_id: switch.living_room_circuit

Building an Energy Dashboard

Home Assistant's dashboard feature lets you visualize TONGOU energy data:

1. Create a new dashboard in Home Assistant
2. Add Energy gauge cards for each TONGOU circuit
3. Include power consumption history graphs
4. Display voltage and current measurements
5. Add automations status and circuit control buttons

This centralized view provides complete electrical system visibility.

Troubleshooting Connection Issues

Device Not Pairing

If your TONGOU smart switch doesn't appear during pairing:

• Verify pairing button was pressed correctly and LED is flashing

Home Assistant Architecture and Installation Options

Home Assistant runs on many hardware platforms. This makes it easy to find an option that fits your skill level.

Home Assistant OS on a Raspberry Pi 4 or Intel NUC gives you the full feature set with add-on support. Docker installations work for users who already run a home server.

The Raspberry Pi 4 with 4GB RAM handles most setups with dozens of devices. For 100+ devices, an Intel NUC gives more headroom. Use solid-state storage instead of an SD card. It is faster and far more reliable for the database writes Home Assistant performs constantly.

Integrating Devices and Services

Home Assistant has over 3,000 official integrations. These cover smart devices, weather services, media players, and cloud platforms.

The built-in discovery system finds many devices on your local network automatically. They appear as one-click setup options under Configuration > Integrations.

Local integrations talk directly to devices without using the cloud. This means faster response times and no downtime during internet outages. Zigbee2MQTT paired with a USB coordinator connects hundreds of Zigbee devices through one integration. Z-Wave JS handles Z-Wave devices the same way, with over 2,000 supported device profiles.

Creating Automations with the Visual Editor

Home Assistant's automation editor uses a trigger-condition-action structure. You do not need to write code for most automations.

Triggers start the automation. They can be time schedules, device state changes, sunrise/sunset events, or webhook calls.

Conditions stop the automation from running when it should not. For example, a nighttime lighting routine can check whether "vacation mode" is on. If it is, the lights stay off even on schedule. You can stack conditions with AND/OR logic for more complex rules.

Energy Monitoring and Dashboard Setup

The Energy dashboard tracks electricity use across your devices over time. Adding smart plugs with power monitoring reveals which appliances use the most energy. Many users find that refrigerators, pool pumps, and HVAC systems account for 60-70% of total home energy use.

Custom Lovelace dashboards put your most-used controls on one screen. Toggle buttons, sensor graphs, and tile cards let you build a layout that fits your needs.

Advanced Automations with Scripts and Templates

Scripts run a sequence of actions with delays and conditions. They work well for multi-step routines. A "movie mode" script can dim lights to 20%, close motorized blinds, turn on the TV, and start the streaming app - each step with a short delay between.

Jinja2 templates let automations use live sensor data. You can set a thermostat temperature based on the time of day and whether anyone is home. The developer tools template editor lets you test template syntax before adding it to an automation.
